Alex and Ronnie are friends and they both attend the same elementary school. Alex lives 3 miles east and 5 miles south of the school while Ronnie lives 6 miles west and 3 miles north of the school. Which coordinate represents the midpoint between Alex and Ronnie’s house?



Answer :

Answer:

Let the school be at (0, 0).

Alex's coordinates: (3, -5)

Ronnie's coordinates: (-6, 3)

Coordinates of midpoint:

((3 + (-6))/2, (-5 + 3)/2) = (-3/2, -2/2) = (-1.5, -1)

(-1.5, -1) represents the midpoint between Alex's and Ronnie's house.
